Inventor: KIMURA MASAHIRO
IPC: H01L21/60
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a bonding device which can increase a yield and reliability of semiconductor devices. SOLUTION: A clamper has a holding frame 10 for holding a substrate 17 as fixed and a support frame 11 fixed to the bonding device by means of screws 6. The holding frame 10 and support frame 11 are provided therein with holes for fitted reception of balls 9 respectively. The substrate 17 is formed therein with a holding part 8 which is projected downwards at a holding window 7. As the clamper is lowered toward a lead frame, the holding part 8 starts to push inner lead parts of the lead frame. A drag is given to the holding part 8 by the inner leads so that the substrate 17 and holding frame 10 rotate around an axis connecting the balls 9. The substrate 17, while changing its tilt through the rotation, gradually pushes the plurality of inner leads, whereby the entire lead frame is evenly pushed.  When all the inner leads are pushed against a heat block, the rotation of the substrate 17 stops and bonding is started.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the self-heating of a gas sensor itself by heating a sensor block housing the gas sensor up to such a temperature as to eliminate the need for the self-heating of the gas sensor itself by a constant-temperature heater with a self temperature regulating function. SOLUTION: Gases in a flue are sucked by suction by a suction filter 2 and introduced to a sensor block 15 via a gas suction pipe 3 and a switching valve 4.

A zirconia O2 sensor 7 measures values of O2 . A constant-temperature heater 17 installed to the sensor block 15 heats the inside of the chambers 16a and 16b with an applied catalyst up to approximately the burning temperature of a gas to be measured.  When the temperature rises, the resistance of the constant-temperature heater 17 is increased and electric power is reduced, and when the temperature drops, the resistance of the constant-temperature heater 17 is increases and electric power is reduced for the consequent self-control of the constant-temperature heater 17. By this, as zero-point fluctuations at the time of calibration become small, it is possible to perform highly accurate measurement.
